    Abstract:
    In February, 1990, a 49-year-old man was admitted with petechia and gingival bleeding. The peripheral blood showed 5,200 leukocytes/microliters including 73% abnormal promyelocytes and 24,000/microliters platelets. Bone marrow puncture revealed that nucleated cell count was 331,250/microliters including 85.4% abnormal promyelocytes with 46XY, i(17q) chromosome. Coagulation tests revealed DIC. He was diagnosed as having acute promyelocytic leukemia, and he was treated with the BHAC-DMP protocol. He achieved complete remission, and received consolidation therapy and maintenance therapy. However, he relapsed in May, 1991 with 46XY, 16q-, i (17q) chromosome. He was treated with BHAC-MV protocol and again achieved complete remission. In June, 1992, he re-relapsed and 3.6% blasts and 10% abnormal promyelocytes was found in his bone marrow. He was treated for 14 days with 15 mg Aclarubicin without any change. Then he was treated with 60 mg All-trans retinoic acid (ATRA). After administration of ATRA, his peripheral blood leukocyte count increased temporarily but bone marrow suppression continued. Then he received continuous subcutaneous infusion of 24 micrograms/day granulocyte colony-stimulating factor (rhG-CSF). After treatment with ATRA and rhG-CSF, he entered a third complete remission.
